The design worked very well and did great service in my own studio for over 20 years.

Let me know if I can be of any further help with the design.

Best wishes,

Hi Richard,
Second Collins welcome and if this is not your liking pls speak up I will not be offended and if I have been too presumptuous pls accept my apologies.

As Richard’s circuit is a very simple job how about a forum member sketching up a pcb layout for project during our house arrest after Christmas.
Way beyond my meagre talents I’m afraid but think some one will be able to do it?
Just a thought in the dull days ‘till New Year.

Anyway
Happy New Year to everyone

Hi RichardB,

Thanks for offering to help. Is the version of the amp you used in your studio still around, and if so could you share pictures ?

I am interested to know how the Hifi World DIY supplement thing worked back in 1994. How did you get from what I assume was your circuit diagram to manufacturing pcbs ? Did you design the pcb, or was the design outsourced with the manufacture ?

Thanks

Mark
